One way to remove lead ion from water is to add a source of iodide ion so that lead iodide will precipitate out of solution: Pb2+(aq) + 2I−(aq) → PbI2(s)

(a) What volume of a 1.0 M KI solution must be added to 120.0 mL of a solution that is 0.23 M in Pb2+ ion to precipitate all the lead ion?

L I−

(b) What mass of PbI2 should precipitate?

g PbI2

(Please show how to work it out step by step)

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?
